ABSTRACT:
A water ski handle system designed to partially absorb and evenly distribute forces generated on the handle component and tow line while skiing. The handle system includes a handle component with two L-shaped corner struts attached to its opposite, opened ends. Each corner strut includes a rigid bushing member which mechanically connects to an end on the handle component, and a perpendicularly aligned long leg member which projects in a forward direction parallel to the longitudinal axis of the main tow line. A continuous, L-shaped inner passageway is formed inside each corner strut through which the end of the tow line passes to connect to the handle component. The corner radius of the inner passageway is relatively large so that point loading on the tow line is substantially reduced. The long leg member is substantially rigid along its horizontal "x" and "y" axis yet sufficiently flexible along its "z" axis which enables the long leg member to bend inward towards the extended longitudinal axis of the main tow line when sufficient tension force is exerted thereon. The tow line exits from handle component from the forward projecting, distal end of the long leg member thereby providing the user a mechanical advantage to prevent rotation of the handle component in the skier's hand during use.
